Printer just destroyed another hotend by freezing filament in the heat brake.
I’m done. No more hotends, no more Bambu. Ever.
I am going to destroy the printer and AMS in a very spectacular way and I’d like to know what you want to see happen to it.
Ganna build a Voron and forget this nightmare company exists.
I don’t want to appear to make assumptions, but is it safe to say that you’re not a happy customer? 
This has absolutely been the worst printing experience I have ever had, and I have been into it since I built a Malyan M300 (monoprice mini delta) myself from a kit years ago.
The entire AMS principle is designed to produce waste and destroy printer parts. There are 3 or 5 small changes that would make this a worthwhile printer that are so extremely obvious from an engineering perspective that I can only assume that it is intentional, especially given the way that flushing volume defaults are configured and behave in BS.
Horrible, overmonetized, works until you have to spend money, which the firmware, printer and slicer all all designed to force you to do.
No more pre-built printers for me. I’d rather suffer my own mistakes than deal with intentional ones.
Before you destroy that machine, you could give it to someone who has not the money to afford a X1.
It’s actually designed to allow color printing and automatic color swaps during a print. Or model/support switches, etc.
You can reduce the purge volume to the bare minimum depending on how much stray color bits you are willing to allow in your prints, or just print monocolor. You don’t have to print multicolor if you don’t want to.
There can be difficulties, obviously. Humidity is a big one that trips people up, and Bambu hasn’t helped anything by shipping some bad batches of filament. But those are just obstacles. The printer really is good (assuming you didn’t get a bum printer).
But what @Glue said - if you are really done with it, why not donate to a local school, a vo-tech, a relative or friend instead of destroying it? Or just sell it for cheap and make someone’s day? Destroying it is wasteful and humans need to learn to be less of that.
I would like to have it if you want to give it away.
If you really want to destroy it, a shotgun would be nice. I hope you make a video to post. 
I’d usually have something positive to say.
Now, I’m not sure I wouldn’t blame you. I seriously considering dropping mine as well.
damn, my printer still works, am i doing something wrong then?
This whole thing sounds like “I know better” rant.
I’m not sure what “freezes” in the hotend means. Heat creep? Clog?
Building a printer from a kit means you put parts together and then added the firmware. It’s not that difficult. I wonder how many of those you built a Rabbit ERCF for and how that worked out. Or did you design your own more efficient AMS?
Forgive me. I fully support your decision to switch, you do you. However, I have to wonder out loud how much is not the printers fault.
At the risk of being chastised and told how wrong I am, I want to guess, just for fun. I bet having all that “experience” under your belt you knew you had to “tweak” things and make them more efficent. How many settings did you “optomize” and change? I’ve seen many come from machines that do need constant tweaking to start messing with these because they’re “pre-built” by people who don’t know squat.
I want to believe this. Will you share those inisights please. no sarcasm.
The only thing I’ve been forced to do (until very recently) is buy filament.
Again, can you share more detail? I mean you sound like a whiz and I’d love to hear how you’d fix this disaster of a printer.
If you still have any hope left you’re welcome to reach out to me. I have felt this same way with the X1 carbon, and with the A1 mini, For various reasons but I have figured them out and both of these machines run, like top-notch phenomenal compared to any machine I’ve ever had before my last machine, I had two snap makers anyways if you have any hope left reach out but if you’re past that, I understand that too have a blessed day
I was thinking tannerite and a high power?
Be sure to make a video of it for YouTube. And then really aggressive destruction, you have to be able to really feel it when you watch it. 
I’ve seen this a lot when people get frustrated with the Bambu printers. It seems more often than not that this is the source of the bad time.
Someone has a bunch of experience messing with all sorts of DIY printers, and so they try and apply that experience to the Bambu printer, but it just throws the experience off and creates a bad time. they blame the printer and fail to realize it’s their own fiddling that messed it up.
The Bambu printer, generally speaking, has a great working baseline. There might be things you can tweak on top of that, but you can’t come into it expecting it to behave like an Ender or whatever. It’s not the same thing.
I know from my own experience of years of fiddling with 3d printers. How you approach a Bambu isn’t how you approach something like an Ender. You are better off forgetting what you thought you knew and go into it fresh. Put everything stock, and print stock. Once you understand it’s base, then you can start pushing it for more.
It’s like you got a new girlfriend, so you’re going to woo her by taking her to Disneyland, because your ex loved Disneyland… Yeah well guess what, your new girlfriend hates Disneyland. You just wasted your time and money and things are worse off because you didn’t take the time to get to know her instead of trying to force your past experiences on her.
Drop it from really high but have the camera at ground level. Ew or from directly below it. Get that incoming first person view ;). Sell it before gen 2 comes out. On craigslist, at $800, it will be gone in a day. Bambus and prusa xl’s never sit for long before they sell. Then quadruple the $800 and get a 500mm ratrig vcore 4 with hybrid drive and idex. Id say thats king atm, but so expensive. Same as the prusa xl or even qidi plus4(although super cheap compared to the other 2 and will have an ams in the next 6 months.)
Nothing else better out there under $5k. The Voron is aged at this point. The plus 4 gives the same or better experience but no multicolor yet. All others in this range are going to be a worse experience like a creality k series or have tradeoffs like a mk4s
This sounds exactly like heat creep to me. I’ve had my extruder jam up like 5 or 6 times from this, esp when I was running the CHT knockoff 2.0. Also printing in my garage where it’s like 45C without opening the door or top on the enclosure. This is sort of a fundamental issue that occurs and user should know how to deal with it, even if it means having a spare cheap extruder on hand. Swapping them on my X1 is like 10x easier than on my ancient Flashforge.
My persistent beef is the problematic VFA, but other than that I have been largely very happy with my X1. If the VFA could be fixed, I’d be thrilled and would unquestioningly buy another one.
That said, before letting this printer be destroyed, I’d be another person in line to buy it, even considering the VFA issues.
To fix extruder jams, I cut out the section that covers the fan. They should have made a duct like the plus4 has. Otherwise, it sucks from the bed and nozzle. stopped all my jamming problems completely for the last 4,000 hours on multiple printers.
You’re on the right track… but I was thinking fill it with tannerite and hit it with a Smart Car. (I’m kidding, that probably wouldn’t be enough kinetic energy to set it off… but if it did it would be quite a show).
Mhm, destruction by repair could be quite entertaining. But considering the issues reported, that’d probably be a short video.
And finally, if you want to go for a different Brand/Printer, why not unclog the nozzle and sell it in good condition?
What AMS savers are the preferred to print?
Sounds like some user error
